UNil'l-E Specificatio To all who'msit may concerns- Belt known that I, DONALD J. MoIN'rosir, a filtlZQll of the United States, residing at- Dentonf in the county of Fergus and State of Montana, have invented certain new and useful improvements in subsoil plows and has for its object to improve the construction and increase the efiiciency of plows of this character without materially increasing the cost of manufacture.

-Another' object resides in the provision of a. subsoil plow, the wheels of said plow being adjustablewhereby the depth to-which the pip; points enter the ground may be regu- A further-object is to provide means for simultaneously directing the ound .wheels and the supporting wheels 0 -the plows."

A stillfurther object is to provide a new" and novel means-for mounting the sod breakin disk gangs. a ith these and other objects in view the invention-"consists of the novel'featuresof- 'const-ruction, combination and arrangement of parts-hereinafter fully described and c1aimed;+and illustrated in the accompany ing drawings, in' which igure 1 is a side elevation of a machine embodyingmy improvements; Fig. 2 is a top plan "iew thereof; Fig. 3 is a section -taken on the line 33 of Fig. 1; Fig. 4 is a: section taken on the line 4-4 of Fig. 1 Fig. 5 is an enlarged detail section taken on the line .5-5 of Fig. 1.

Referring more particularly to the drawings 5 indicates the plow beam of the for- "-'war'd"or main plow. This beam is mounted upona' transverse bar or axle 6 and is rigidly scarred-thereto. A substantially U-shaped plate-7 i's'secured on the forward end of the plow .beam and has its ends pivotally connected bymeans of a transverse bolt or pin.

Upon this plate a tongue 9 is secured and is adapted to oscillate longitudinally. A

' clevis 10 is also secured to the plow beam to which the draft bar is adapted to be attached. The, ends of the transverse axle bar 6- are connected to the forward end'ofthe plow beam by the rods 11, said rods each being" formed in two sections connected by net Letters late'zitr I mus s filed June 25,". 1910;; ,seri a'i Ito assists; Y

An axle spindle 13;. is r otatably mounted in one endof the bar 6-..andcarries one of the ground wheels l'. A- 'rack segment 15- is secured to the bard and a lever 16 is pivotally securedto the racltsegment andcarries theusual spring actuatedpawl for engagement .with the teeth thereof. A short rod 17 connects this lever to the axle spindle and a tension spring 18 is arranged on said rod normally tending to hold the-wheel intoengagemeut with the ground; Upon' the manipulation of the lever 16 the axle spindle 7 is rotated and the wheel. raised, the-spring H 18 absorbing all shocker jar to the machine in the adjustment of the wheel. This ad-v justment of the wheeltogether with the adj'ustment of the, otheriground wheelland theplow supporting wheels. permits of theregui lation of the plow'points so that they maybe engaged in the ground to-any desired depth. Uponthe other end of the bar 6 an axle spin le'19 is verticallymovable in-the .80

bearing 2 secured thereon." This spindle has mounted upon its lower and the other of the ground wheelsvl. Tlieupper end of the spindle 1-9 is 'laterally extended to pro- ;vide 'ahandle 21." A .platex22'f-isloosely mounted upon the axle spindle .19. This plate is provided with a pluralityof open'-- ings 2-2" which are adapted to receive a f 1 spring controlled lockingbolt' 23 carriedby the handle 21. Thus the axle spindle may be readily rotated in its bearing to turn the wheel and is locked by the en agement of the bolt in one plate22; Y v I A lever 24 is pivoted upon a rack segn'ient .95 25 formed upon afsleeve 26 through whicl'r the axle spindle-19 extends. This sleevensr nv arranged between collars fixed 'to--the..-sp -n-'i dle whereby vertical movement of the spin-v dle through the sleeve is prevented. One end of the lever is pivoted to an arm 24! secured to the bar (it-said. lever carrying a spring controlled dog for locking engage- 24 is raised or lowered, the axle spindle 19-=-=105j and the ground wheelca-rried thereby will also be raised and lowered. v

A rod 27 is rigidly securedto thei glow; I

of the openings of the beamifiland thegbar v6 and .tq this rod one I end of a curved; downwardly extending bar or rod 28. is secured and carries apluralityof sodz-breakin disks 2 9.- These disks are yieldingly hel in engagement with the ground bymeans of a leaf spring one end of which is securedtojthe bar and the other end'toithe undersi fof the' transverse axle bar 6. IA single disk '31 is-also disposed ad- .jacentftoi'the disk gang 29 and is carried by r the .lowerjend of .ajrod 32 rigidly-secured sod breakingldislis-are arranged in advance at its upper end-tothe plow beam 5. The

of and. adjacent to the-mold board 33 wl1icli is of the usual-construction and is secured to the rearlowerend of the plow beam.

A band or yokel34 .is secured to the plow -beam,.immed1ately above the mold board andja vertically disposed rod 35 ismounted 'in .the rearwardly extending intermediate portion ofithisband. The central portion rod. rod :and ugh.- t e of the band which surrounds the to .is cut away to receive a collar 36 c'arriedby the This collar is rigidly'secured'onfthc revents its vertical movement sleeve formed by the band.

The lower .end' of the rod .angularly' disosed and :has" mounted thereon a supportmg wheel 37; which engages with the ground j 4 A1 clevis -38-is loosely carrie 39 and the mold and supports. the rear end of tie plow.

by the rod 35 andhas connected theretothe rear subsoil -plow.. This low. consists of the beam rd 40. t The beam also carries a single barrow diskx41 rotatably mounted-in the lower end ,of a. rod 42 rigidly secured to. the beam.

' The mold. ard ,40-i sadapted to trans- -versely disposed out of alinementwith the forward: mold board if desired by means ofa lever rThislever. is rigidly secured at its lower end to a rod44 carried by a plate 45 pivotally fixed'to the plow beam 39. This rod extends through'the connecting member .46 which connects therear plow tothe front low. A rack- 47 is forme upon the memer 46, the teeth of which are adapted .to be en aged by a'pawl carried by the lever where y the plate .45 may be held in its adjusted position. By moving the lever- 43, the plate 45 is swung'upon t e pivot rod 44 and the point of theplow deflected to one side of the direct line of movement of the machine. The plateis adaptedto be connected to the end of the beam. 39 by means of a suitable 'clevi's as. clearly illustrated in 1. A rod 48 ismounted upon therear low beam 39 in a similar manner to the 35 and. has arranged on its lower end a' wheel 49 which' engages with the ground and'supports the rear subsoil. plow.

Alever-50 ismounted upon a rack segment 51 secured to:.the forward plow beam 5 and isfconnectedby means'of the rods 52 to. the upper end of the axle spindle 19 and advance of the plow the rods 35 and 48. Thus by manipulating the lever 50, the ground' engagingwheels may be simultaneously""directed whereby the direction of movement ofithe plows is shifted at the same time.

. The drivers seat 53 ismounted upon the rear end of the beam 5 and is sodisposed that the various levers may be readily reached for the adjustment of the parts.

As shown in 'Fig. 2 of the drawings the 5 rear plow of the machine-is adapted to be disconnected-from the end of'the beam 5 to V be arranged at one side of the front plow, a clevis being secured upon'the transverse axle barb 'to which the end of therearplow beam maybe connected. A rod 52 connects the rod 48 of the plow to the lever 50 in, the, same manner as when the plow is arranged in the nearer the forward plow so that said plows may be simultaneously. ad- 35 justed. By arrangingthe plows in thismanner, a complete gang plow is provided when the nature of the work to be performed may require the same.

The rear plow may be veryeasily and quickly connected and disconnected in its different .po-

sitions.

, By-the arrangement of the colter gangs on each sideof. the plow beam 5, the sod'willbe thoroughly brokenupon opposite sides of 5 the points of the. plows. The plows areso adjusted hat when the machine is being operated, the disk gangs cut up the. sod in.

oints. The. first of,

the plowst-hen turnst loose u'pper crust of the-earth over, whereby the same is thoroughly broken. The second oi the plows which follows in the same furrow turns up the subsoil or thesoil beneath..the. .upper layer of earth, the loose upper soil .-:be1ng'10:

thrown to one side so as to leave a clear furrow for the rear plow. Thus the under soilis thoroughly broken up and the seed 'which is sown in the ground is thus allowed will be understood that the same is su's- 'ceptible of many minor modifications without departin .from the spirit or sacrificing any of the a vantages -thereof.

The rear plow may also be independently adjusted by means of a lever 55 which is connected by a rod 56 to the clevis 38 'vertically m-ovable on the rod 35. The beam- '39 maythus be raised or lowered to reguframe,
